Forms in websites that give you responses in three steps

For all my unexperienced programmers out there trying to make themselves a site you prob know that if you just put a form there it will not give you the answers when someone uses it. To make it give you the answer follow this tutorial.

Step1:

index.php

Type this above all code on the entire page. This goes outside of the at the top of the file

<?php
//This will make you able to create session variables
session_start();
?>

Step 2:

index.php

To make your form appear on your site use this code

<form action="form.php" method="post>
<!-Your form text space->
<input type="text" name="text">
<!-Your submit button->
<input type="submit" name="submitBtn">
</form>

That will make the form appear on your site. That one is just a text bar and submit button.

Step 3:

form.php

For the PHP part. This part will make it where when a person submits the form it will create a new file named response.txt and will show you what they said.
type this only in the PHP file

<?php
//creates session variable out of text
$_SESSION['response'] = $_POST['text'];
//opens response.txt
$file = fopen("response.txt", "w");
//Writes what they said
fwrite($file, $_SESSION['response'];
//Ends the writing process
fclose($file);
?>

Now when you wanna check if anyone has responded to your form go to response.txt and it will have everything that has been said in the form.
